if you are tired of VC coast ocupying everywhere here is a beautiful mod from Prussianwarfare that fixes this here https://steamcommunity.com/sharedfiles/filedetails/?id=1700909876
below a FAQ I copied from the steam page
1) Is this mod save compatible?
Yes it is, as the mod does not touch startpos
2) What is the mod not compatible with?
This mod specifically overrides the vanilla occupation options for the Vampire Coast, but it doesn't override their climate. Thus, any mod that overrides the occupation options for the Vampire Coast in the culture_settlement_occupation_options will not be compatible.
3) Well, what about the campaign overhaul I use? (Grimhammer, Lucky's, Vox Populi, Radious, etc.)
I have no clue as I don't use campaign overhauls, but as conservative guess would be no. If there is enough interest in a particular overhaul, then I will consider making the mod compatible.
all credits to prussian warfare and the ones who helped him, I am merely sharing it
It's much easier and more fun to get engrossed in lore that takes itself seriously and tries to make sense within its own frame of reference.
the reason I prefer LOTR over warhammer fantasy and 40k
